Question

Keycloak策略执行程序无法与示例Sprint引导应用程序一起使用。

我正在使用Keycloak版本6.0.1，并尝试集成示例Sprint引导应用程序（Sprint引导版本2.1.3）。我的目标是在Keycloak中设置策略和权限，并在示例Spring引导应用程序中使用Keycloak策略强制程序，以便使用Keycloak中定义的适当权限自动执行所有授权决定，而示例应用程序中无需代码。

我的示例spring boot应用程序仅从内存列表中打印用户列表：

public class JPAUserResource {

    @Autowired
    private UserRepository userRepo;

    @GetMapping(path = "/jpausers")
    public List<JPAUser> retrieveAllUsers() {
        return userRepo.findAll();
    }
}

我的application.properties文件具有以下内容：

server.port=38080
spring.jpa.show-sql=true
spring.h2.console.enabled=true
logging.level.org.springframework.security=DEBUG
logging.level.org.keycloak.adapters.authorization=DEBUG
#Keycloak Configuration

keycloak.policy-enforcer-config.paths[0].path=/jpausers
keycloak.policy-enforcer-config.paths[0].methods[0].method=GET

我的Keycloak授权设置如下：

{
  "allowRemoteResourceManagement": true,
  "policyEnforcementMode": "ENFORCING",
  "resources": [
    {
      "name": "Default Resource",
      "type": "urn:login-app:resources:default",

        "/*"
      ]
    },
    {
      "name": "jpausers",
      "ownerManagedAccess": false,

        },

        }
      ]
    }
  ],

    {
      "id": "94518189-3794-451c-9996-eec22543d802",
      "name": "Default Policy",
      "description": "A policy that grants access only for users within this realm",
      "type": "js",

      "config": {
        "code": "// by default, grants any permission associated with this policy\n$evaluation.grant();\n"
      }
    },
    {
      "id": "0242cf72-365d-49ae-8d5b-4ced24736f24",
      "name": "test_jpa",
      "type": "role",
      "logic": "POSITIVE",
      "decisionStrategy": "UNANIMOUS",
      "config": {
        "roles": "[{\"id\":\"jpa\",\"required\":false}]"
      }
    },
    {
      "id": "5c34e2b4-a56a-45f9-a1cc-94788bcb41b0",
      "name": "test_perm1",
      "type": "resource",
      "logic": "POSITIVE",
      "decisionStrategy": "UNANIMOUS",
      "config": {
        "resources": "[\"jpausers\"]",
        "applyPolicies": "[\"test_jpa\"]"
      }
    }
  ],
  "scopes": [
    {
      "id": "4ee351e6-7095-453a-a4f4-badbc9ec1ba0",
      "name": "GET",
      "displayName": "GET"
    },
    {
      "id": "9119aab2-75a0-49d1-a076-8d9210c3e457",
      "name": "POST",
      "displayName": "POST"
    }
  ]
}

当我向Rest API'/ jpausers'发送请求时，请求失败，并在控制台上显示以下消息：

*19:17:52.044 [http-nio-38080-exec-1] INFO  o.k.a.authorization.PolicyEnforcer - Paths provided in configuration.

UMA授权被禁用。我首先使用具有密码凭证授予类型的Openid Connect令牌API检索了访问令牌，然后尝试使用访问令牌访问Rest API'/ jpausers'。

有人可以在这里帮助解决此问题吗？我该如何解决？我必须启用UMA才能使策略执行器起作用吗？

Answer 1

快速浏览一下，我可以看到您在application.properties中的映射未完成，您还没有将HTTP方法映射到在keycloak中配置的作用域。像这样的东西

keycloak.policy-enforcer-config.paths[0].path=/jpausers
keycloak.policy-enforcer-config.paths[0].methods[0].method=GET 
keycloak.policy-enforcer-config.paths[0].methods[0].scopes[0]=GET

Answer 2

我认为您缺少keycloak.securityConstraints [0] .securityCollections [0] .name = jpausers

Answer 3

我遇到了同样的问题，我能够在我的应用程序属性 yaml 文件中使用类似的设置来解决它，如下所示：

    keycloak:
      security-constraints:
        - auth-roles: 
          - "*"
      security-collections:
        - name: 
          patterns:
          - /*
